More recently, using a BCL1 murine lymphoma model, Dahal et al. [28] were able to show that the lymphoma created a tumour suppressive microenvironment that had an adverse effect on anti-CD20 antibody directed treatment that was due, at least partially, to an increase in the expression level of inhibitory FcγRIIB on tumour associated macrophages (TAM). Here, FCGR2B is linked to lymphoma.
